Endovascular management of bleeding iliac artery pseudoaneurysms complicating radiation therapy for pelvic malignancies.
OBJECTIVE
We evaluated arteriographic findings and endovascular treatments of eight patients who had bleeding iliac artery pseudoaneurysms and who had undergone radiation therapy (3000-6500 rad [30-65 Gy]) and surgery for pelvic malignancies.


CONCLUSIONS
Angiography revealed contrast media extravasation in 75% of patients who had bleeding iliac artery pseudoaneurysms and failed to show the source of bleeding in 25%. The patients who had positive findings at angiography were all successfully treated percutaneously, although two patients required additional bypass surgery. Among embolic materials, coils and balloons were safe and efficient, whereas cyanoacrylate was unsafe and led to complications in two of three patients. A covered stent, which was not available for most of our patients, was used in one patient and may be an effective means of treating pseudoaneurysms.
